Peptide-Carrying Nanoparticles Cure Degenerative Eye Disorders

In one of only two studies of its kind, a study from researchers at Tufts University School of Medicine and the Sackler School of Graduate Biomedical Sciences at Tufts demonstrates that non-viral gene therapy can delay the onset of some forms of eye disease and preserve vision. The team developed nanoparticles to deliver therapeutic genes to the retina and found that treated mice temporarily retained more eyesight than controls. The study, published online in advance of print in Molecular Therapy, brings researchers closer to a non-viral gene therapy treatment for degenerative eye disorders.

Scientists Identify Molecular Mechanism that Maintains Important Feature of Spindle

During cell division, microtubules emanating from each of the spindle poles meet and overlap in the spindle’s midzone. Scientists at the European Molecular Biology Laboratory (EMBL) in Heidelberg, Germany, have uncovered the molecular mechanism that determines the extent of this overlap.
